9. MIDI Control

This chapter describes the options you have available to control the Pulse via MIDI.
You will find a glossary at the end of the manual. It explains the various terms used
herein. If you have any questions about MIDI and MIDI messages, consult the
glossary.

9.1 Calling Programs via Program Change

All of the Pulse's sound programs can be called via MIDI Program Change messages. As the
device contains 100 program locations, it recognizes program numbers 1...100.
Program number 100 is a random program.
The Pulse has a special feature: A sound is not interrupted during program changes.
This feature can be used creatively. Please note that a program change takes approx.
40ms.

9.2 Influencing Sounds via Control Change Messages

There are two ways MIDI Controllers influence sounds:
• Controllers can be used as modulation sources.
• Controllers can change sound parameters directly.
Controllers as Modulation Sources
The Controllers Modwheel and Breath Control are always used as modulation sources. The
freely definable Control X function can also be used as a modulation source. The X stands
for a globally defined Controller number 1...127. The following parameters are suitable for
this application:
Cutoff Mod Source, Pitch Mod Source, Mod Unit 1...4 Source

Changing Sound Parameters

Every parameter is assigned a Controller number through which the parameter can be
changed. If a parameter is changed at the device, then this change is sent along with the
appropriate Controller number via MIDI. This is especially helpful when you want to record
changes you made at the Pulse to a sequencer.
All controller messages are sent and received via the channel defined in the MIDI Channel
parameter. The appendix of this manual contains a table listing the Controller numbers and
the sound parameters they are assigned to.

9.3 Pitchbending

The Pitchbend Scale lets you define to what extent a pitchbend message influences the
pitch of the Pulse. Pitchbend is also available as a modulation source.
